Reaction Steps

5-Methyl-2-(6-chloro-pyrimidin-4-yl)-2H-pyrazol-3-ylamine (2.09 g, 10 mmol) was mixed with methyl amine (40% in water, 9 mL) and 2-propanol (30 mL). The mixture was heated at 50° C. in a sealed tube. After 4 h, the reaction mixture was cooled to room temperature and condensed, triturated with water, and filtered. The solid was washed with water, air-dried to give [6-(5-amino-3-methyl-pyrazol-1-yl)-pyrimidin-4-yl]-methyl-amine (2.08 g, Yield 97%): 1H NMR 400 MHz (d6-DMSO) δ 8.80 (s, 1H), 7.44 (s, 1H), 6.82-6.74 (m, 3H), 5.19 (s, 1H), 2.83 (s, 3H), 2.06 (s, 3H); MS m/z 210.64 (M+1).
